Hi,
I have this almost working perfect.

I have a grid with a GridButtonColumn.
When the user hovers over this GridButtonColumn the tooltip popups up with LoadOnDemand information taken from a ProductID field in the grid.
This is all great... however !

The grid is pager style and when i select page 2 and hover over the 1st row.. it shows the information for the 1st row in page 1 ????

My code for adding controlID to the RadToolTipManager is below...
(Cell 4 is the column i hover over)

Any ideas please ?
Thanks
Mark

Sub grdProduct_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grdProduct.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = e.Item

RadToolTipManager1.TargetControls.Add(e.Item.Cells(4).ClientID, item.GetDataKeyValue(

"ProductID").ToString, True)

End If

End

Sub

Hi Mark,

When you change the RadGrid's page, you actually display new records which have different target control ID. In order to achieve the desired behavior, you should update the RadToolTipManager's TargetControls collection. I assume that in your case the RadToolTipManager stays with the old values when the page is changed.

One possible solution is to clear the TargetControls collection in the RadGrid's PageIndexChanged event handler by adding the following code:

  protected void RadGrid1_PageIndexChanged(object source, GridPageChangedEventArgs e)  
    {  
        RadToolTipManager1.TargetControls.Clear();  
    } 

In case this does not help, please prepare a sample, fully runnable reproduction project (including DB, if needed), open a new support ticket and send it to me. Once I receive it, I will modify it in order to meet your requirements.



All the best,
